Any advice for signing raw tx?

+2 votes

Hello all, 

I am working through the examples for working with raw transactions. I'm using createRawSendFrom + signRawTransaction to send a native asset, but I'm missing something. signRawTransaction appears to return the original TX, unmodified. 

  • The addresses I am sending to & from are both in the wallet
  • to has receive, from has send permission
  • from address has sufficient funds 
  • the selected output for vin has enough assets

Following are JSON formatted results of the operations & a couple queries I tried to sanity check.  I'm using v2.0.2 running in a docker container; I'm using the multichain-node RPC client to make calls. 

Any ideas re: where to dig next are appreciated. Thanks!

If it helps; these are the calls: 

createRawSendFrom 1RVWQ3v8n6ffRWh4Ve9eRNZDdDZmbDq27uSSRW {1Dr8yVKr8wizJF6t3kF65qJctTN7uQxXsrwhFE: {'': 5}

signRawTransaction <txhex>

Actually, the issue was a little more subtle / not with multichain. I'm using a multichain-node client, and a call to signrawtransaction with just tx-hex (i.e., default params) would actually send a request for

signrawtransaction <tx-hex> ,,,ALL

this will not sign the tx; it needs to be just a request for

signrawtransaction <tx-hex>

to get the expected behavior.
